Application June 7, 1952, Serial No. 292,310

3 Claims. (Cl. 29465.5)

This invention relates to improvements in devices for transferringmagnetic materials from bulk to a place of use.

It has for a principal object the provision of a tool carrying a magnetadapted to be reciprocated therein, said tool having a non-metallicplate in one base thereof positioned to be contacted by the magnet inone of its extreme positions, whereby said magnet mayhold magnetizablearticles while they are being transferred to another point, and meansunder the operators control for moving the magnet to its other extremeposition out of contact with said non-metallic plate, thereby releasingthe magnetic articles.

Another object of the invention is the provision of a magnetic device ofthe character described wherein the magnet is positioned in arectangular chamber, andwherein a manually actuated lever extends intosaid chamber through a slot in one wall thereof for moving the magnet toa position remote from the base thereof.

Other objects and advantages of the invention will be apparent to thoseskilled in the art.

Referring to the drawings, which are given by way of example toillustrate the invention:

Figure 1 is a plan view of the device as seen from above;

Figure 2 is a cross sectional elevation of the device, taken along theline 22 of Figure 1;

Figure 3 is a sectional elevation taken along the line 33 'of Figure 2;and

Figure 4 is a view of the device taken from below.

The device includes a casing which is somewhat U-shaped in form, havinga solid depending portion 11 on one end thereof, and having a hollowdepending portion 12 on the other end thereof. The portion 12 has acavity 13 formed therein which is closed by a nonmagnetic plate 14secured to the portion 12 by means of escutcheon pins 15, or in anyother suitable manner. The upper end of the cavity 13 has a curved wall16 which conforms .to the upper end 17 of a horseshoe magnet 18; thewall 19 of the cavity 13 has a vertical slot 20 formed therein.

Extending into the cavity 13 via the slot 20 is a lever 21 having aball-shaped end 22 which'engages the inner surface 23 of the magnet; andthe other end of this lever has a hole 33 formed therein. A bolt 24having a head 25 formed thereon extends upwardly in a hole 26 formed inthe body 10, and has, engaging the threads thereon in spaced relation tothe head, a nut 27 forming a clearance between the head and itself. Theupper end of the bolt 24 is engaged by a second nut 28, which is setinto the counterbore 29.

Operation The form of the invention shown in the present application isparticularly adapted for use by upholsterers, and with this devicetacks, of which upholsterers use 2,760,809 Patented Aug. 28, 1956 largequantities, are usually bought'in bulk, and the use of this deviceeliminates the former method of picking up the tacks in bulk with aspoon, putting them into some kind of a container, moving them to apoint of use, and dumping them out in a suitable receptacle.

With the present. device the portion containing the non-metallic plate14 is placed in contact with the tacks, for instance in bulk, with theresult that a large number of tacks pile up on the plate 14. Then thedevice is moved over to a receptacle at the point of use, the operatorengaging the horizontal portion between the portions 11 and 12, and whenthe group of tacks are over the receptacle at the point of use, theoperator may then pull upwardly on the handle 21, thereby raising themagnet upwardly until the upper portion thereof is in contact with thecurved wall 16 of the cavity, thereby removing the magnetizing forcefrom the vicinity of the plate 14. Now, since the magnetizing influenceis removed, the group of tacks falls off the device and lands in thereceptacle at the point of use.

By the use of this device tacks may be transferred much more rapidly andwith less chance of injury to the worker because there is no reasonforhim to put his hands in contact with any tacks while making suchtransfers.

Although I have here shown and described one form of the device by Wayof example, I do not wish to be limited to the exact form shown, as manyvariations may be made in the device within the scope of the followingclaims. I

What is claimed is:

1. In a device of the character described, a generally U-shaped bodyhaving a horizontal portion with depending portions on each end thereof,one of said depending portions having a cavity formed therein, aU-shaped magnet reciprocally carried in said cavity, a non-metallicplate forming a closure for'the lower end of said cavity, and a leverbeneath said handle and pivotally connected to said body adjacent to theother of said depending portions and having a portion extending intosaid cavity in a position to engage and raise said magnet when saidlever is pulled upwardly toward the handle by a user.

2. In a device of the character described, a body having a portionforming a handle, a portion angular with respect thereto and having acavity formed therein, a wall of said cavity adjacent to said handlehaving a vertical slot formed therein, a non-magnetic plate forming aclosure for said slot and the lower end of said cavity, a magnetreciprocally carried in said cavity, and lever means adjacent to saidhandle and extending through said slot and operatively engaged with saidmagnet and having a portion thereof adjacent to said handle, said magnetbeing normally positioned in contact with said plate and adapted to bemoved to a position spaced apart therefrom by the actuation of saidlever means, said lever means being comprised of a rod having anenlarged rounded end engaging said magnet and having a hole adjacent tothe opposite end and engaged with bolt means extending through saidhandle.

3. In a device of the character described, a body having a portionforming a handle, a portion angular with respect thereto and having acavity formed therein, a wall of said cavity adjacent to said handlehaving a vertical slot formed therein, a non-magnetic plate forming aclosure for said slot and the lower end of said cavity, a magnetreciprocally carried in said cavity, and lever means adjacent to saidhandle and extending through said slot and operatively engaged with saidmagnet and having a portion thereof adjacent to said handle, said magnetbeing normally positioned in contact with said plate and adapted to bemoved to a position spaced apart therefrom by the actuation of saidlever means, said handle having a depending portion spaced apart fromand substantially to the portion carrying the magnegwhereby a users handengages the handle between said portions and said device maysit substanti'all y level when not in use.
